Answer: Associative Property of Addition

We basically have 2+x+y on each side. The difference is the use of parenthesis in different places. With addition, we can add in any order we want and that includes grouping terms as well. For example
(2+3)+5 = (5)+5 = 5+5 = 10
2+(3+5) = 2+(8) = 2+8 = 10

So that's why in general (2+x)+y = 2+(x+y) is true for all real numbers x and y.

Find the length of the arc intercepted on the unit circle by the following central angle. 0=5π
Brums [2.3K]

well, since arc's length is s = rθ where θ is in radians, and in the Unit Circle r = 1 and we also know that θ = 5π radians, then

s = (1)(5π)

s = 5π.

Courtney constructed this figure using a compass with its width set equal to PR, the radius of the circle. She claims triangle P
murzikaleks [220]

Answer:

B

Step-by-step explanation:

It helps if you have the figure included. However, since it is not, we can assume that she has gone around the circle with all six sides of the hexagon is set to PR.

That makes the hexagon with 6 equal sides. It also makes each triangle using one of the sides equal to PR. The radii are all equal. There are 6 triangles making up the hexagon.

Both statements she makes are true and that makes B the answer.
